How many moles of sulfur are in 80 grams of sulfur?

Answer 1

About #2.5" moles"#

#"Number of moles"# #=# #"Mass"/"Molar mass"#

#=# #(80*g)/(32.06*g*mol^-1)# #=# #??mol#

Note that sulfur likely exists in its elemental state as #S_8#. I am perfectly justified in treating sulfur as #S#. The number of #"sulfur atoms"# is the same in each case.

Number of moles = Mass of sulfur / Molar mass of sulfur Number of moles = 80 grams / 32.06 grams/mole Number of moles ≈ 2.494 moles Hence, there are roughly 2.494 moles of sulfur in 80 grams of sulfur. To find the number of moles in 80 grams of sulfur, divide the mass (in grams) by the molar mass of sulfur, which is approximately 32.06 grams per mole.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
